Comment (by simonpj):

 > The `PprFlags` change might be easier if these functions took
 `PlatformConstants` as an argument (which would then become part of the
 `PprFlags` structure).

 Surely if the functions take `PlatformConstants` as an argument, then the
 Cmm stuff becomes independent of choices of `DynFlags` and `PprFlags`?

 So why would this flag make `PlatformConstants` part of `PprFlags`?  And
 more generally, is that a good place for `PlatformContants`?  Doesn't
 sound like a place I'd look.
